Licensed 2-bed Hospital

Mercy Hospital's MACC facility is a licensed 2-bed hospital, officially named Mercy Hospital, Orchard Park Division, offering 24/7 emergency care services.

The MACC differs from an urgent care center because it is considered a hospital, and therefore, can accept ambulances and patients with severe and/or life threatening illnesses or injuries. The MACC has access to around-the-clock cardiac and stroke services at nearby Mercy Hospital of Buffalo.

A difficult 2 1/2 years of seeing experts and having costly, painful treatments had left my mom's stage 4 wound in very poor condition. 

Several doctors, nurses, and specialists had treated her, stating, "She will have this wound for the rest of her life, just try to keep it clean." Another expert said, "Keep her in bed, up for meals only."

For weeks and weeks, my mother could not sit in her favorite chair, play her games, do her crafts, go out shopping, or a visit with family. She had no quality of life. 

Dr. Rohan, mom's primary doctor, had learned of the Advanced Wound Healing Center that had recently opened in Orchard Park, New York. He called me and insisted that I take her there ASAP.

She was seen immediately by Dr. William Lagaly.

He did a full assessment of her and started her on a treatment plan. This treatment plan was an antibiotic solution that Dr. William Lagaly had put together himself. After years of no movement to heal, this stage 4 wound began to close. Dr. William Lagaly found just the right treatment.

Today, I heard, "This wound is healed!" I just can't believe it!

This is an exceptional doctor who is an expert in his field. He is caring, considerate, and most of all, he invests himself in his patients (a rare trait seen today). His staff is wonderful!

This office is clean, bright and beautiful. I can't express enough thanks to this wonderful doctor and the staff.

Please, if anyone has a skin or wound problem of any kind, go to the Advanced Wound Healing Center in Orchard Park NY. We are so fortunate to have this facility in Western NY.
